111 cant open smtp stream

Description: Connection refused or inability to open an SMTP stream.

What does this mean?

This error is typically referencing a connection issue to the remove SMTP/Mail server. Often in relation to firewalls or misspelled domains.

How to fix SMTP Error 111?

As in most cases, you’ll want to ensure that the email address being sent to is spelled correctly (especially the domain name in this case). Upon confirming that is correct, attempt connecting to the remote SMTP server from a local machine (computer) other than your server to see if you are able to connect to that server. If you are unable to connect from your local machine it’s most likely an unresolvable issue at the remote (recipient) email server.

You should be able to send now if you were on the level server.

1. I get this error when I send email from squirellmail:
